Abstract
On the basis of the sedimentary characteristics and reservoir distribution law in Feixianguan Formation of Upper Permian-Lower Triassic,East Sichuan Basin, it can be determined that the characteristics and distribution of Changxin reefs and Feixiangguan oolitic banks are tighly relevent to the fluctuation of sea-level.The Changxin reefs developed during the rapid rising of sea-level on the ramp and inner ramp. When the growing speed of the reefs was lower than the rising one of sea-level,catch-up transgression reefs were formed,and when growing speed of the reefs was quicker than the rising one of sea-level,keep-up transgression reefs were formed.The Feixianguan oolitic banks were formed on the inner platform rim and some inner platform areas during the regression of sea-level, single platform rim banks were distributed widely and thickly,although the inner platform banks were of large number,they were thin and narrow in range.So,development formations of Changxin reefs rose towards transgression direction,and the Feixianguan oolitic banks migrated towards platform expandtion with regression. The Formation was deposited in a large scale of fluctuation of sea-level,the transgression begun in the early Wujiapin period, sea-level rose rapidly in the Changxin period ,and it reached summit in the early Feixianguan period,then lowered down in the following Feixianguan period until to the end of the time.
